Application filed April 10, 1924. Serial No. 705,507.

This invention relates to metallic receptacles and the method of making the same, and particularly with respect to the class of receptacles known in the art as kegs.

T e primary .object of the invention is to so construct the keg blank that a number of the blanks may be nested together within a small space and thereby save considerable in ship ing losses.

The invention further and more specifically comprehends the forming of the keg blank in a semi-circular manner, which up on a slight contraction may be quickly and easily 'oined to form a complete circular recept e. I

' Another object of the invention is the provision of turned over upper and lower portions of the metallic material to constitute a reinforced top and of the keg adapted to withstand rough usa e.

fiumerous other objects of the invention will be apparent from the detailed description following when read in conjunction with the attached drawings forming a part hereof, in which Figure 1 is a erspective view of the blank showing initial bending.

Figure 2 is a similar view showing a further step. in the formation of the device. Figure 3 is a similar view showing the device crimped and bent in a semi-circular shape ready for shipment.

Figure 4 is a view of the device be sprung together to form the body of barrel.

Figure 5 is an elevation of the complete barrel.

- Figure 6 is a perspective view of one of the barrel ends. 1

Figure 7 is a similar view of one of the retaining v v Figure 8 is an enlar ed fr entary sectional view of the device; an

Figure 9 is an enlarged view of the device partly'in section.

Referring now more particularly to the drawings 1 represents the body blank made of the desired material, which is preferably a galvanized or black tin metal, approxiready to the ends thereof are bottom portion.

First, in that they serve mately 22 or 24 ga e. about 40 inches long g! 20 inches wi e, as clearly shown in igure 1. The metallic blank is initially bent near the upper and lower end thereof to form reinforced up er and lower parts 2 and 3, the pur ose 0 which will be more fully explained ereinafter. The sheet is thence placed upon a suitable press and the unched out, as at 4, 5, 6

t the circular retainin rin hereinafter referred to may be utilize suc punched out portions constituting a continuation of the radius of the outwardly extending grooves 7 and 8. The blank is thereafter passed between a machine ossessing the necessary instrunientalities or impressing the grooves 7 8, 9 and 10, and preferably by the same operation bending the sheet into substantiall a semi-circular formation as disclosed inhigure 4 of the drawing. Cooperating laps 11 and 12, which are reversely turned, are then formed in such a manner that upon the compression of the barrel body to the desired extent the ends may be securely and readily interlocked to form the completed body, as illustrated in Figure 5. It will be noted that the grooves 7, 8, 9 and 10 constitute external c0rrugations. Additional grooves are formed, preferably by the same operation which forms the grooves aforesaid, and such additional grooves are designated by the reference numerals 11' and 12'. T e purpose of the grooves 11' and 12 which pro'ect inwardly b0 y is twofold. as a reinforcing and secondarily,

and 7, in order t with respect to the metallic means for the barrel body, they rovide coop'eratin metal ic keg bottom an top 13 and 14 re spectively, which bottom and top is pro vided with depending flanges. 1'5 and 16 adapted to fit upon the shoulder formed by the grooves at the points 17 and 18.

After the metallic body structure has been sprung into a true circular form, as disclosed in Figure 5, and the cooperating lips 11 and 12 have been interlocked, the top and bottom are placed in the position disclosed in Figure 8. In order to securely hold the shoulders for the top and bottom in place the invention contemplates the use of a retaining ring 19 oi any suitable character. However, it is preferred that this retaining ring shall be of the construction illustrated in Figure 7 and provided with outwardly 1plro'ecting terminals 20 and 21. The meta 'c ody'is when such a type of retaining ring is use provided with recesses 22 and 23 into which the terminals aforesaid may be placed, and the normal tendenc of expansion of the retaining ring it" securely and forcibly maintain the ring within the grooves 8 and 9 and thereby eiiectually lock the bottom and tog from accidental displacement. The punche out rtions i, 5, 6 and 7 permit the ring to uni ormly engage Within the groove of the tops and bottoms, irrespective or the longitudinal folds of the metallic receptacle con; stituting the interlocking means therefor. The position of the ring in use is clearly illustrated in Figure 5 of the drawings.

Byv bending the metal intermediate its ends to form the upper and lower circumferential laps 2 and 3, I obtain an effectual reinforce for the keg at the bottom and top thereof adapted to "withstand the heavy usage to which receptacles of this character are subjected.

It will be obvious to those skilled in the art that in. order to remove the top and bottom it is only necessary to first displace the retaining rings by the insertion of any sharp instrument and to thereafter remove the bottom and top thereof. The kegs a shipped in a semi-circular form and in t manner considerable storage space is saved. To set up the keg it is onl necessary to sprin the same together an hook the reverse y bent folds, Which are bent lon tudinally of the keg. Thence set the en down inside of the keg below the reinforce upper extremities gland 25 until the flanges of the tops andghottoms contact with the inwardly extendifi grooves formin projections 17 and 18 out e interior of theieg and then applym the rin rin s. 1

t be obvio us to those skilled in the art that many changes in construction and arrangement of parts may be used without departi in the 0 owin Having thus 5 we claim is:

2. A metal ic receptacle, comprising a body portion provided With longitudinal interlocking means, said body portion being normally of a substantially semi-circular shape, but said body portion being adapted to be sprung into substantially a circular formation and being retained in such osition by the engagement of said interloc g means, a closure removably positioned wit in each end of the body, a split rin engaging. each closure to retain it in pface and also to prevent relative longitudinal shifting of the engaged interlocking means, and means for preventing the split in the ring from shifting into register with the inten locking means.
